that movement el' the'handle 23 causes the movable lining 2, the scrapers in the creamcan, and the ice-stirrer 17 in the central freezing-can to be operated. It lis also obvious and also the central freel/.ingcau are Asta- I provide some V-shaped ribs Qt, secured tothe movable lining 2 and extending into" the spaeebctiveen such movable lining and These ribs earl-,v the ice and salt about the cream-can and keep it well stirred andfdistributed.

From the foregoing description the purpose ot' my invention. can be seen, namely, having .ay lircezing-surlfaee within the bod,vof the cream, as well as outside of it,.so that the speed of the freezing process will be doubled.

i worked and light.

v upon the central freezing-can, as well as the Scrapers, can be Withdrawn from theel-cani by taking hold of the upper end of the sha-ft 1l. and lifting the Whole out ol the crean'i-can.

If one does not wish touse the-central 'freezing ,receptacle or can 7 for refrige'rating or freezing purposes, by leaving out the ice and salt and using the can as a core or similar object forthe purpose ol' taking up space in the center of the can, I am enabled to freeze the cream much sooner than if it were in a solid body,beeause the body of the cream is thinner and the freezing-surface is greater in proportion to the amount of cream than if it were all in a solid body.

lVhat I claim as my invention, and desire to seeureby Lef-ters Patent, is-

l. In an ice-cream freezer, a suitable outer receptacle, and a cream-can centrally secured within such receptacle, a movable lining for t-he outer .receptacle having on it ribs for distribu ting the ice, and means for rotating such l movable lining.

lthat/[he outer vessel or bucket, the cream-can,

3. In an ice-cream freezer` a suitable outer vessel, a cream-can secured within the saine,

a movable lining for the vouter receptacle having secured to it ribs for distributing the ice and also having on its'upper end an outvwardly-extending annular ilange, friction rollers mounted in the upperend of such outer receptacle on which the flange of the movable lining mayberotated, and means lror rotating such movable lining.

ll. In an ice-cream freezer, an outer ice-receptacle, a cream-can mounted therein, an icereceptacle within the cream-can, arms extending down intothc 'cream-can that are triangular in crosssection, a pair of springaetuated Scrapers mounted on such arms which scrape both the inner and 'outer walls of said cream-can.

,4. An icecream freezer' eomprisingau outer receptacle, a movable lining therein having ribs for stirring the "ice, a stationary creamenn mounted within the receptacle, astationary 'freezing-reeeptaele mounted within the cream-can, a shaft extending down into the inner freezing-receptacle having a wing on it to stir the iee therein, a head mounted on the upper end of such sha ftand Within the cream-- can so as to be rotated by said shaft, arms extending down from said head and carrying vsuitable Scrapers, anda handle-bar secured to the movable lining and to the upper end of said central shaftwhereby when said handlebar is rotated lthe movable lining with the ribs, the serapers, and distributer in the eentral .i'reezingaeeeptacle will all be rotated.

In witness whereof I have hereunto set my 1 hand' this 7th day of March, 1896.
